WELL-DRILLING vIVIACHINE.

SPECIFICATION forming part of Letters Patent No. 763,824, dated J une28, 1904.

Application led October 31, 1903.

T all whom, it may concern:

Be it known that I, HUGH H. WILBURN, a citizen of the United States, anda resident of North Yakima, in the county of Yakima and State ofWashington, have invented a new and Improved Tell-Drilling Machine, ofwhich the following is a full, clear, and exact description.

This invention relates to improvements in machines for drilling wells,and it particularly relates to an improved and novel construction ofwalking-beam for operating` the tools, a main object being to provide awalking-beam with which a gasolene or steam engine may be successfullyused for well-drilling, so shaped and hung as to cause the drilling-toolto move in direct perpendicular lines, thus preventing the rope or cablefrom rubbing against the sides of the well and wearing the rope or cableaway.

I will describe a well-drilling machine embodying my invention and thenpoint out the novel features in the appended claims.

Reference is to be had to the accompanying `drawings, forming a part ofthis specification,

in which similar characters of reference indicate corresponding parts inall the figures.

Figure 1 is a sideelevation of a well-drilling machine embodying myinvention. Fig. 2 is a side view of the walking-beam employed. Fig. 3 isaplan View of the beam-carrier. Fig. 4 is a plan view of the machinewith the upper structure and the supporting-wheels removed. Fig. 5 is adiagram illustrating the movements of the walking-beam. Fig. 6 is afront view of certain guides, and Fig. 7 is a detail plan showingtemper-screw-supporting hooks employed. p

Referring to the drawings, 1 designates the frame of the machine,mounted on the front wheels 2 and rear wheels 3 in the usual manner.Supported at the front end of the frame is a gasolene-engine 4, on theshaft of which are balance-wheels 5. Also on this shaft is a pulley6,-from which a band 7 extends to a driving-pulley 8 on a shaft 9,having bearings Looselymounted on the shaft 9 is a sprocket-wheel 10,from which a chain 11 extends to a sprocket-wheel 12 on the shaft of asand-drum 13, the said sand- Serial No. 179,315. (No model.)

drum shaft having its bearings in boxings attached to the uprights 14 onthe rear end of the machine.l

The sprocket-wheel to operate the sanddrum is designed to be driven atintervals by the shaft 9. As a means for causing the movement of thesprocket-wheel with its shaft I provide it with a friction clutch memberdesigned to b`e engaged by a clutch member 15, movable lengthwise ofsaid shaft, but rotating therewith. This clutch member 15 may be engagedwith the sprocket-wheel by the usual shifting lever.

Also loosely mounted on the shaft 9 is a pinion 16, engaging with agear-wheel 17 on a counter-shaft 18. The pinion 16 is provided with aclutch member 19, designed to be engaged by a clutch member 20, mountedon the shaft 9 and designed to rotate therewith, but movablelongitudinally thereof and shifted in the usual manner.

Attached to the shaft 9 is a friction-pulley 21, designed to be engagedwith a frictionwheel 22 on the shaft of a rope or cable drum 23. Theshaft of this drum 23 has its bearings in ashifting box 24, so that thewheel 22 may be moved into engagement with the pulley 21 when it isdesired to raise the tool from the well, or it may be shifted intoengagement with a brake, here shown as a pulley 25, for holding the drumstationary. A rope or cable 26 extends from the drum 23 over an idler 27at the forward end of the machine and attached to a shaft 28, havingbearings in uprights 29. From the idler 27 the rope extends aroundapulley 30, having bearings in the upper portion of the walking-beam, tobe hereinafter described, and from this pulley 30 the rope extends overa sheave 31 at the upper end of the uprights 14 and thence to thetemper-screw 32.

The walking-beam 33 in of triangular shape, and at its upper forwardportion it has swinging connection with a carrier consisting of beams34, mounted to swing on the shaft 28 and converging toward the walking-beam. The lower end of the walking-beam is con- ,nected to a wrist-pin35 on the gear-wheel 17,

rights 14. These guide-bars obviously will prevent any lateral movementof the walkingbeam during' its up-and-down movements. At its outer endthe walking-beam is provided with hook members 37, designed to receivetrunnions 38, attached to the temperscrew. These hooks 37 are mounted toswing on a bolt 39, so that the hooks may be swung laterally when thetool is to be removed from the well. To hold the hooks in position tosupport the temper-screw over the well, I employ pins 40, which passthrough an opening in the block portions of the hooks and into anopening in the walking-beam.

As before stated, a main object of this invention is to cause directvertical movements, or substantially so, of the walking-beam. In Fig. 5I have illustrated diagrammatically the up-and-down movements. The endof the beam, beginning at l, travels up to 4". Then the gear-'wheel 17will have traveled oneeighth of a revolution from 4a to 5, and the endof the walking-beam at this time is stationary, thus giving the tooltime to rise. It will be seen by 5, 6, 7, and 8ab that when the end ofthe beam starts down at the proper speed it travels a little ahead ofthe tool. This gives a free and clear drop, and it will be noted from 8uto l that there will be a retard of the beam, which gives the tool timeto reach the bottom of the well.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a well-drilling machine, a walkingbeam oftriangular form, a carrier to which the walking-beam is pivoted, andmeans for causing vertical movements of said walkingbeam, substantiallyas specified.

2. In a well-drilling machine, a triangular walking-beam, a carrier withwhich the beam has swingingI connection, a gear wheel, a wrist-pin onsaid wheel for engaging the lower end of the walking-beam, adriving-shaft, a pinion loosely mounted on said shaft for engaging withthe gear-wheel, a clutch mechanism for causing movements of the pinionwith the shaft, and a motor on the machine for driving said shaft,substantially as specified.

3. In a well-drilling machine, a walkingbeam of triangular form, acarrier with which said walking-beam has swinging connection, meansforcausing the vertical movements of the beam, vertical guides for saidbeam, and devices on the beam for engaging with a temper-screw,substantially as specified.

4. In a well-drilling machine, a triangular walking-beam, swinging beamscarrying said walking-beam, a gear-wheel, a wrist-pin on said wheelengaging with the lower end of the beam, adriVing-Shaft, a pinionloosely mounted on said shaft, and engaging with the gearwheel, a clutchon the shaft for causing a rotary movement of the pinion with the shaft,

and a gasolene-engine for driving the shaft,

substantially as specified.

6. In a well -drilling machine, a drivingshaft, a gasolene-engine havingdriving connection therewith, a triangular walking-beam operated fromsaid driving-shaft, a sand-drum, a sprocket-wheel loosely mounted on thedriving-shaft, a sprocket-wheel on the shaft of the sand drum, a chainconnecting said two wheels, and a clutch member on the drivingshaft forengaging with the sprocket-wheel, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
